Original High Point Acorn Mirror Nuts

[Ironhorse]

Have not seen just the high point acorn nuts listed to the parts board but seems everyone is always wanting to find originals and original high point acorn nuts don't seem to be easy to find. Nice to have spares on hand if one is lost or a rusted and crusted mirror arm snaps. Have had these for some time now and am at the point I don't think I will be building any more trucks. One set (4) white painted acorns, one set (4) of polished stainless steel acorns and one partial set of of three (3) non-polished stainless steel acorns. All have good threads internally. Any thoughts as to value for them as set of 4 each and partial set of 3?

Even though the thread is 3/8 NC they are slightly different from standard nuts.
Hard to find and difficult to reproduce exactly.
$5 dollars each? Just a guesstimate.
